CNC Controlled Filament Winding Machines: Precision equipment used for primary and secondary coil winding of tungsten filaments for light bulbs. The Primary Filament Winding Machine (PCM-008) features ultra-high-speed rotation of 10,000-50,000 rpm, mandrel adjustment from 20-500um, and pitch adjustment from 10-200um. This equipment incorporates direct drive technology and high-frequency motor spindles, characterized by low noise, economical maintenance, and maximum bobbin capacity. The Secondary Filament Winding Machine (SCM-3500) offers ultra-precise pitch determination through a computer control system, eliminating the need for lubricants and minimizing wear parts. It provides speeds of 700-3,500 rpm, mandrel adjustment from 0.05-0.5mm, and pitch adjustment from 0.05-0.5mm. The Automatic Filament Cutting Machine (FC-941) performs high-speed cutting of continuous and LEG coils, with enhanced cutting precision through computer control technology and high-sensitivity optical sensors.CNCControlledFilamentWindingMachines:Precisionequipmentusedforprimaryandsecondarycoilwindingoftungstenfilamentsforlightbulbs.ThePrimaryFilamentWindingMachine(PCM-008)featuresultra-high-speedrotationof10,000-50,000rpm,mandreladjustmentfrom20-500um,andpitchadjustmentfrom10-200um.Thisequipmentincorporatesdirectdrivetechnologyandhigh-frequencymotorspindles,characterizedbylownoise,economicalmaintenance,andmaximumbobbincapacity.TheSecondaryFilamentWindingMachine(SCM-3500)offersultra-precisepitchdeterminationthroughacomputercontrolsystem,eliminatingtheneedforlubricantsandminimizingwearparts.Itprovidesspeedsof700-3,500rpm,mandreladjustmentfrom0.05-0.5mm,andpitchadjustmentfrom0.05-0.5mm.TheAutomaticFilamentCuttingMachine(FC-941)performshigh-speedcuttingofcontinuousandLEGcoils,withenhancedcuttingprecisionthroughcomputercontroltechnologyandhigh-sensitivityopticalsensors.
